| * | xtensa: move oprofile stack tracing to stacktrace.c | Max Filippov | 2015-08-17 |
| | | | | | | | | | Old oprofile interface will share user stack tracing with new perf interface. Move oprofile user/kernel stack tracing to stacktrace.c to make it possible. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com> | ||
| * | xtensa: provide custom CALLER_ADDR* implementations | Max Filippov | 2013-05-09 |
| | | | | | | | | | | | | | | | | Definition of CALLER_ADDR* through __builtin_return_address makes compiler insert calls to __xtensa_libgcc_window_spill, which in turn makes fast_syscall_spill_registers syscall that clobbers registers when called from the kernel mode, leading to invalid opcode exceptions on return to userspace. Provide definition for CALLER_ADDR0 as MAKE_PC_FROM_RA(a0, a1) and in case CONFIG_FRAME_POINTER is enabled extract CALLER_ADDR{1-3} from stack.
